' citizen l'ofthe United btates, and a resident l Ianew and improved 'lubricating means for the air cylinderv of an air pump which may be placed in ,tlre carb of a locomotive and which will feed the lubricating material 'to the cylinder only when the pump is work- 1n g i A further object of my invention y1s to provide a new `and improved form of'lu'briJ catingf`device` especially adapted. for useon locomotives iorlubricating the air cylinder of the air'compressor, the device being provided with a suitable means whereby the lubricating material is fed uniformly andin any ,desired amount, the lubricating' material being ,maintained in a suitable chamber free'from the rassure of the air cylinder,

Vand being su ied tothe cylinder intimately mixed with tie air and in fine particles.`

It hes'been 'a difficult matterv to properly lubricate the air cylinder of an air com'- pressor on accountl of the varying pressure ,of the :air within this cylinder, most of the" devices previously in use being affected in their operation by this varying pressure being communicated thereto; in myimproved form of device I makeuse of this varying pressureas the 'actuating means for efecting thefeed of the lubricating material to theV air' cylinder.

The use and operation of my device is as' follows.: The lubricat'or shown in Fig. 2 is osition. and prefshown in- Fig. 1. The pipe from the outlet 15 is connected to the air cylinder ofthe compressor and the oil chamber 2 is filled i 4o with ade'sired amount of oi-l by turning the .removable cap 40 which uncovers the opening 41 inthe cover 5. When the com ressor begins to work and when the air -wit in the air cylinder is bein compressed, the pres- 45 surels transmitted t rou h the pipe to the '.outlet 15 andwill force t e valve 18 in the chamber 17 into closed position as 4shown in Fig.- 2, this pressure a so communicating with the piston 12 in the chamber 11, thereby forcing the piston rod 14 upwardly and turnin t e-spindle 30 by. means of the dog 33, suc movement brin ing the dog 31 at the opposite end thereo downwardly Aand y moving the-feed-rod 4 so that the flower end ymi 5 thereofjis forced inte the cavity 2l; it has reviousl .been stated that the pocket 10. a 'ac'ent t e'lower end of the feed rod .,v and t e opening 9 contained in the sleeve f8 are registering so that a suitable amount of. .oilA may lindits way. into this pocket 10 to vbe; jlater ldischarged into -the cavity 21 whenthe feed rod l4 moves down as just described.' During the rarefaction of the air within the' air c' lnder of the compressor 65 en the .inert v stro e of -theipiston the pres' ent structure; if the ppc is` lent parts shown in sure Ywithin the outlet 15 and the chamber 17 and the chamber 1l will be reduced and the Spring 5 within 'the oil chamber 2 will bring the lower end of the feed rod 4 back to the position shown in Fig. 2, this reduction of 7 0 pressure also permitting the valve 18 to come out of engagement with the seat 23 whereby the oil .previously dischar ed into the cavity 21 is permitted to ow out th-rough the openings 24, 24', whence it is 15 drawn along intothe air cylinder together with' the air flowing therethrough-whereby the pressure is equallzed, the air vent 22 com- I municating with the cavity 21 providing a suitable source of this air. These operations justdescribed are Arepeated durin each compression and rarefaction stroke o the piston 1n the air cylinder of the compressor,'=the dogs 31 and 33 nioving upwardly and down wardly, and since the lubricator is within `=.the cab such movement of these dogs is a convenient indicating means to those in the db that thev air compressor is working. By fixing the relation of the set screw 36l and the locking nut 37 wlth relation to the sup- ,90

porting member 35, the upward travel of 'h the dog 33-is determined, this also determinin the downward movement of the dog 31 an 'the travel of the feed rod 4,- thereby regulating the amount of oil to be fed into the cavity 21 at each compression stroke of the compressor.

In vplace of the spindle with lthe dogs thereon, shown in Figs.-2 and 3, I have provided a modified form and means, as shown in Fi 4, which comprises, the lever '30. suitaby pivoted at its central ointl to a' spindle 29', the opposite ends o this lever or walking beam being adapted for engage# ment with the upper ends 27 and 28 of the 105 feed 'rod 4 and the piston rod 14; the opera- A tion of my device' when' provided with .this form of Vconstruction .is not substantially different from the o eration of the equiva- I igs. 2 and 3,'the pur- 11.0 pose ofthe lever 30 or the spindle with the dogs thereon being merely to move the feed rod 4 down at certain intervals which are determined by the upward travel'of 'the piston rrod 13. The regulating device for deter- 11`5 mining the amount of travel of the feed rod 4which embodies the set'screw 36 with the lock nut 37 and the supporting member 35 may be conveniently retained 1n this form of construction. 120

From a consideration of the structure and operation of my device it will be notedthat by suppl. ing the desired* amount of lubricant to tl e-cavity atstated intervals, which lubricant is carried on tothe cylinder byfthe inrush of air supplied thereto, that' 'this lubricant will, be.i1f.timatelgt `mixed with the air a'ii'd will. bel susper'id. therein in' the form of smallfparticleswhereby it is bodily carried into the .cylinder, not being allowed 139 o and that in place of the various 'elements claim as new, and desire to secure by Letters shown I .may supply 'their equivalents in a mechamcal sense vwithout departing from the spirit and scope ofmy invention as defined in the followingclaims.
